South Korea welcomed the nomination of Janet Yellen to be Federal Reserve chairman and said that she will need to weigh the effects on other nations of reducing U.S. monetary stimulus.

“She has rich experience and an impressive resume as a policy maker,” Choi Hee-nam, director general of the Finance Ministry’s international finance bureau, said by phone from Sejong on Wednesday. “I expect her to consider well the ripple effects on other countries” from policy decisions such as altering the Fed’s bond-buying program, Choi said.

Asian officials are grappling with risks associated with Fed policy shifts. Emerging-market stocks plunged after May 22, when Chairman Ben S. Bernanke signaled that stimulus may be pared, and then rebounded after the Fed last month continued its quantitative-easing program. (Bloomberg)
